Specific interactions based on this mirror-image property of the interacting polymers have been observed in other enantiomorphic polymer mbctures. Precipitation has been reported when enantiomorphic solutions of the polypeptide poly(y-methyl d- and L-glutamate) (known to be or -helical) at 1% concentration in dimethylformamide (DP = 1700) were mixed at 100°C. Mixing in different proportions gave a precipitate, the weight of which corresponded to twice that of... 

These results confirm the potential of poly (p-formyloxystyrene) as a useful resist material combining such interesting properties as ability to be imaged in both positive or negative tone, ease of preparation, and activity in the deep UV, with a moderate sensitivity and good contrast. 

Poly(vinylcarbazole), of course, is the polymer that is generally utilized in electrophotographic imaging processes such as xerography, but the polymer is not totally satisfactory from a mechanical viewpoint (Section 1.11.2.1.1). Better strength, flexibility, ozone resistance and adhesive properties were said to result by utilizing a modified poly(epichlorohydrin)... 

The fluorescence of polysilanes has received much attention in recent years, in part because of the discovery that some poly silanes are electroluminescent, and so may have applications in display technology. Fluorescence spectra, quantum yields, lifetimes and other properties for dialkylpolysilanes have been thoroughly investigated by Sun and coworkers.98 Dialkylpolysilanes exhibit fluorescence of a rather normal type, in which the emission is a mirror image of the absorption, with a rather small Stokes shift. This suggests that the emission takes place from a highly delocalized state, probably an...
